Positive and negative, would be one category of them, but primes and non-primes would be another, and evens or odds, another.

Only integers (whole numbers) can be primes. A prime is a number that is only divisible by 1 and itself. 43.2 and all other decimal numbers are not divisible by 1.

Negative numbers are not considered primes. Prime numbers are defined for positive integers. The smalles prime number is 2. by Alexis Assad

There is no particular characteristic that is common to such numbers other than they are positive integers greater than or equal to 4.

Yes. In fact, all positive integers (except primes) can be represented as the product of prime numbers. In this case, 224 = 2 * 2 * 2 * 2 * 2 * 7

30, which is the smallest positive integer divisible by the first three primes: 2, 3 and 5.

6 because it is divisible by 2 and 3.

There are 4 and they are 2 3 5 and 7

There is no such number. If you restrict yourself to integers, there are numbers - such as primes, that are not divisible by an integer other than one. And if you do not restrict yourself to intgers, then there is no smallest number sincce given any number, half that number will be smaller and will be a divisor.

They are composite positive integers. They are semi-primes.

There is none. The only even Prime number (even meaning divisible by two, and primes being numbers divisible only by the integers 1 and themselves) is 2.

There is none. The only even prime number (even meaning divisible by two, and primes being numbers divisible only by the integers 1 and themselves) is 2.

A composite number. Actually, all integers have at least two factors. Even primes are divisible by 1 and themselves.

no the smallest number that is divisible by four different primes would be 210

All primes are integers, but all integers are not prime.
